In this you can see is_complete key in data array so I want check is_complete for object if any one object have 0. I want to do something and how do I know that my all is_complete are 1. Please guide me I am doing like this but it is not working for me.
{this.state.mealData.map((item, index) => {
if (item.data.length == 0) {
null;
} else {
if (item.data?.some((v) => v.is_complete == "1")) {
return (
<View><Text>Want to show button here if and only if all is_complete are 1 if data empty in dome array then we are not counting it</Text></View>
);
} else {
null;
}
}
})}

CodePudding user response：
you can use the function every or can reverse the condition, like:
item.data?.some((v) => v.is_complete != "1")
and put the text in the else block
if (item.data?.some((v) => v.is_complete != "1")) {
null;
} else {
return (
<View><Text>Want to show button here if and only if all is_complete are 1 if data empty in dome array then we are not counting it</Text></View>
);
}
CodePudding user response：
This is how you can do it. In cleaner way.
{
this.state.mealData.map(
(item, index) => (
item.data.length &&
item.data.every((v) => v.is_complete &&v.is_complete == "1") &&
<View><Text>Data</Text></View>
)
)
}

Works for me:
let _mealData = {
"meals_completed": [],
"meals": []
};
d.Data.meal_data.forEach(m => {
// _mealData.meals.push(m);
// you could use the line above to add all meals (even if nothing is in the data of it)
if(m.data.length < 1) return;
m.data.forEach(m2 => {
_mealData.meals.push(m2);
m2.is_complete === "1" ? _mealData.meals_completed.push(m) : "";
})
});
if(_mealData.meals_completed.length === _mealData.meals.length){
// do your stuff
